raw oak tree slices

I just had an oak tree cut down and I made some 2" slices to make picture frames and table. I would like to know how to preserve the oak wood slices, to help prevent cracking and the bark from falling off when drying. Or do I need to let the wood dry before doing anything to them. What is the best way to beable to sand and cut and preserve the wood and when can I polyurethane the pieces. Also what products would I use.

Whether or not you have not had it sawn into boards, it is important to seal the ends asap! Wood starts cracking quickly after tree being cut down. I use plain ole canning wax from the grocery store. I have had bad experience with latex paint as sealer. Once sliced, boards should be placed on strips of wood between each layer, placed in an area that air circulation is good to help drying porcess. Be sure to cover the stack. One year for every inch of thickness is usually recommended. Apply finish after cutting and dry-fitting. I do not know about the bark issue.

No guarantees the bark will stay on...but the best way to keep the bark on is to harvest the tree during the winter when the sap has gone back down into the roots. Are you in a colder climate? If so, you're in an ideal position.
